WARP-BEAM FOR LOOMS.

SPECIFICATION forming part of Letters Patent No. 785,386, dated March21, 1905.

Application filed August 17, 1904. Serial No. 221,120.

To all whom it may concern:

Be it known that I, ALBERT J. TrIoRNLEY, a citizen of the United States,residing at Pawtucket, in the county of Providence and State of RhodeIsland, have invented a newand useful Improvement in Warp-Beams forLooms, of which the following is a specification.

-This invention has reference to an improvement in looms, and moreparticularly to an improvement in warp-beams for looms.

The object of my invention is to improve the construction of warp-beamsfor looms, thereby lightening and strengthening the warp-beam.

A further object of my invention is to construct a more rigid anddurable warp-beam than has heretofore been done.

My invention consists in the peculiar and novel construction of awarp-beam having a sheet-metal cylindrical drum, sheet-metal ends,fittings forming the end shafts, each having a circular concentricgroove for the ends of the cylindrical drum, means for securing thewhole together, consisting of bolts extending through the ends,fittings, and drum, and other details of construction, as will be morefully set forth hereinafter.

Figure l is a face view of my improved sheet-metal warp-beam. Fig. 2 isan end view of the warp-beam, showing the stamped-up flange and ribs forstrengthening the end. Fig. 3 is a transverse sectional view taken online X X of Fig. 1. Fig. 4 is a longitudinal sectional view taken online Y Y of Fig. 2; and Fig. 5 is adetail sectional view of amodifiedform of flange for the end, showing the edge of the flange rolled underto strengthen the same.

In the drawings, a indicates the sheet-metal cylindrical drum; 6 Z), theend fittings; c c, the sheet-metal ends, and (Z (Z the fastening-bolts.The cylindrical drum (6 is formed from a sheet of metal having the holea by rolling the sheet and bringing the abutting edges (0 (0 together,forming a cylinder having the open ends a a The fittings b b are in theform of a disk, each having the concentric circular groove 6 b in theirinner face for the ends a a of the drum (0 and the outwardly-extendingshafts 6 6 having the central longitudinal holes 6 If, as shown in Figs.3 and 4. The circular ends 0 c are stamped from sheet metal, each havingthe flange c c, the radial strengthening-ribs 0 c and the central hole 0c for the shafts 6 6 as shown in Figs. 2 and L. The fastening-bolts (Z dextend lengthwise through the drum a, holes in the fittings b b, and theends 0 c and secure the ends a a of the drum a in the circularconcentric grooves 12 I) in the fittings b b and the sheet-metal ends 0c to the fittings by the nuts d d, as shown in Fig. 4. If thoughtdesirable, the flange c on the circular ends 0 0 could be strengthenedby rolling the edge of the flange under, as shown in Fig. 5.

In the use of my improved warp-beam the end of the warp-threads areknotted and secured to the drum a through the hole a in the drum. Thewarp-beam is supported by the shafts b b in bearings on the loom in theusual way or. by a rod through the longitudinal holes 6 b in the shafts6 6 It is evident that the cylindrical drum (0 could have a plurality ofholes corresponding 'to the hole a and could be of any length requiredwithout materially affecting the spirit of my invention.

Having thus described my invention, I claim as new and desire to secureby Letters Patent 1. A warp-beam having a hollow drum constructed fromsheet metal, fittings having a circular concentric groove andoutwardly-extending shafts, circular ends having a flange andstrengthening-ribs stamped from sheet metal, and fastening-boltsextending through the drum, fittings and ends, as described.

2. In a warp-beam, the combination of a hollow drum constructed fromsheet metal the abutting edges of which extend lengthwise of the drum,fittings having a concentric groove and an outwardly-extending shaft inwhich is a longitudinal hole, circular ends having a central hole, aflange and radial strengtheningribs stamped from sheet metal, andfasteningbolts extending through the drum, fittings and ends, asdescribed.

3. In a warp-beam, the combination of a sheet-metal drum a having thehole a, the abuttingedges a a and the open ends a a, the fittings I) I)each havinga circular concentric groove 6 and a shaft 6 in which is thehole 6 the sheet-metal ends 0 0 each havinga flange 0', radialstrengthening-ribs 0 and the central hole 0 and the fastening-bolts (Z dextending through the drum, holes in the fittings and ends secured bythe nuts d cl, as 16 described.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

ALBERT J. THORNLEY. Witnesses:
